When it comes to commercial buildings, protecting the exterior from water damage is essential to maintain the building’s integrity and longevity. Water damage can lead to costly Repairs, health hazards, and decreased property value. Fortunately, there are several exterior waterproofing solutions available that are tailored specifically to commercial buildings. In this article, we will explore these solutions and the benefits they offer.
What is Exterior Waterproofing?
Exterior waterproofing is the process of protecting the exterior of a building from water damage. This technique involves creating a barrier between the building and the outside environment to prevent water from entering the building’s foundation or basement. Waterproofing the exterior of a commercial building helps to prevent water intrusion, which can lead to mold growth, foundation cracks, and other issues that can harm the building’s structure.
Why Do Commercial Buildings Need Waterproofing?
Commercial buildings, like any other structure, can be vulnerable to water damage. The consequences of water damage in a commercial building can be more severe than in a residential property. Commercial buildings are often larger, with more intricate systems and components than residential properties, and any damage can be more expensive to repair. Additionally, commercial buildings often have many people working inside, so water damage can pose a health hazard for employees and visitors.
Water intrusion can also damage inventory, equipment, and documents, which can lead to a loss of revenue for the business. In some cases, water damage can even force businesses to shut down temporarily while repairs are being made.
Types of Exterior Waterproofing Solutions for Commercial Buildings
Several types of exterior waterproofing solutions are available for commercial buildings. Each solution has its benefits and drawbacks, and the best solution for your building will depend on several factors, including the building’s location, design, and construction.
1. Cementitious Waterproofing
Cementitious waterproofing involves applying a cement-based coating to the exterior of the building’s foundation or basement walls. This coating creates a dense, impermeable barrier that prevents water from penetrating the surface. Cementitious coatings are often used to waterproof concrete and masonry surfaces and are ideal for below-grade applications.
Benefits:
- Extremely durable and long-lasting.
- Resistant to root penetration.
- Chemical resistant.
Drawbacks:
- Can crack over time.
- Can be costly.
2. Liquid Membrane Waterproofing
Liquid membrane waterproofing involves applying a liquid coating to the exterior of the building’s foundation or basement walls. This coating cures to form a flexible, seamless membrane that resists water penetration. Liquid membranes are ideal for irregular surfaces and easy to apply, making them an excellent option for buildings with unique designs.
Benefits:
- Can be applied to almost any surface.
- Flexible and can accommodate movement.
- Easy to apply.
Drawbacks:
- Susceptible to punctures and tears.
- Requires special skills for application.
3. Sheet Membrane Waterproofing
Sheet membrane waterproofing involves attaching sheet membranes to the exterior of the building’s foundation or basement walls. Sheet membranes are typically made of rubber, PVC, or other synthetic materials and are highly resistant to water penetration. They are ideal for large surfaces and areas that need seamless and uniform protection.
Benefits:
- Durable and long-lasting.
- Highly resistant to water penetration.
- Resistant to root penetration.
Drawbacks:
- Can be difficult to install.
- May require special tools.
4. Bentonite Waterproofing
Bentonite waterproofing involves applying a thin layer of bentonite clay to the exterior of the building’s foundation or basement walls. When wet, the clay expands to form a dense, impermeable barrier that prevents water from penetrating the surface. Bentonite is ideal for below-grade applications where there is a high water table.
Benefits:
- Self-healing properties.
- Non-toxic.
- Long-lasting.
Drawbacks:
- Can be affected by soil conditions.
- Requires special expertise to apply.
FAQs
- Do all commercial buildings need exterior waterproofing?
Not all commercial buildings need exterior waterproofing. However, it is recommended as a preventative measure to protect the building’s structure and its occupants from water damage.
- What is the most cost-effective waterproofing solution?
The most cost-effective waterproofing solution will depend on several factors, including the building’s location, design, and construction.
- Is exterior waterproofing a one-time fix?
No, exterior waterproofing is not a one-time fix. Eventually, the coating will need to be reapplied, and regular Maintenance is required to ensure that the waterproofing barrier continues to protect the building’s structure.
Conclusion
Exterior waterproofing is an essential aspect of maintaining the integrity and longevity of commercial buildings. There are several exterior waterproofing solutions available, each with its benefits and drawbacks. Choosing the right solution for your building will depend on several factors and requires the expertise of a professional. Investing in exterior waterproofing solutions can save you time and money in the long run and ensure the safety and longevity of your building.
